New Rock Breaker And

Driller

ANEW device, of considerable interest to those who have to drill holes in or break rock is now being market ed in Australia. It is an automatic rock breaker and rock-driller, which is com pletely self-contained and so designed as to replace the old expensive type of air compressor, with its long pipe lines. The cost is but a fraction of that of the old type of compressor plant.

The light weight of the units enables them to be easily transported, and no time is lost in having pipe lines from the compressor to the field of operations.

They are ready for work as soon as they are taken to the field, and they can be used practically for any type of rock breaking and drilling, also for road con struction.

The spade attachment of the drill does drilling in hard ground and does away with the use of a pick.

They deliver 1,500 blows per minute.

Many hundreds of them are in use in construction of aerodromes and in the Postal Department of the United King dom.
